双万向联轴节联接主从动轴等速条件

Condition of constant speed drive between driving and driven axle in bi-universal joint connection

本文应用矢量分析的方法，研究了双万向联轴节联接的主从动轴旋转运动，得出了等速传动条件。其结果与传统的观点不同。

Using the method of vector,the revolving movement of driving axle and driven axle in bi-universal joint connection is studied to derive the condition of constant speed drive lt is different from traditional opinion.On this base,constant speed drive condition of universal shaft in spatial arrangement is analysised also.
